Ok so I got my very first order of resurrectors from CCV and I am loving this thing- it has a fantastic hit. Before buying I read many threads here about keeping them wet don't let them get dry and burn they need refilling more often etc. With my natural caution, I used the syringe provided filled to just under 2 ml and have been vaping on and off for six hours ! I tried two times to top it off or reuse the syringe to add juice but as soon as I did juice started dripping out the bottom. How often after the first fill will these need refilling and how will I know without wasting juice that it does? How many times a day on average? How many days do these usually last? I am using a simple 3.7 volt box mod. Thanks for any help this is my first 510 cartomizer period as I use 808's on the other device.
